Path to a directory should return 404

[nchainani]

Under the document root, I have few directories like
<root>/1/file1.html
<root>/1/file2.html
<root>/2/file1.html
<root>/2/file2.html

If I go to the url http://localhost:8080/1, I get back a 301 with the
new location http://localhost/1/     autoindexing is off, and so I end
up with a 403 Forbidden page.

Can I change this default behavior such that all the requests for the
directories get the universal 404 page i.e. instead of a redirection, it
should simply return the configured 404 page for location /.

Sorry, I couldn't find a similar post on the forums. Thanks for any
pointers.
